i just tested my n64 emu and it also not working :/ when it used to be. it has to be an isos i updated which was provided by usbloadergx. all my other stuff still read my usb like. wiimc/nes/gameboy/snes/wiiexplorer/usbloadergx.

so i have to imagine it has to be some isos that wii64 and wiisx use to use since they both made by the same person.

ok after doing alot of google serach apparently i have isos 58 which wii64 and wiisx isnt compatible with but i also have 202 installed? so why isnt it reading from 202 :/

I had the exact same problem: WiiSX wasn't reading from my USB drive. Fortunately, I came across lovewiibrew's thread about the issue: http://www.wiihacks.com/emulators/69...i64-wiisx.html. You guys need to download the USB 2.0 mods of WiiSX and Wii64. Not only will they be able to load from your drives once again, but they're considerably faster. Check lovewiibrew's thread to get the mods.

What Wiisx do you use??
beta1
beta2
beta2.1
What version is your wii??
4.2/4.3
and what ios did you install for it?
Im no pro, just a 40 year old good n00b, i had problems with beta 2 and 2.1 they did not load from my sd card, i know its not a usb but the load is the same.
Beta1 did work for me.
Maybee this can help.
I have softmod on a 4.3E system.
